Adjustable ring

ABSTRACT

An adjustable finger ring may include a ring head having through holes on the bottom a first shank having shank collars as support at one end and a split portion at the other end, and a second shank having shank collars as support at one end and a split portion at the other end. The split portions may complement and overlap each other in an operative condition of the ring. A spring can be fitted inside the two supports with the coils of the spring aligned with the holes of the support of the first shank so as to allow a pin to pass through. The inward facing surfaces of the collars of the second shank may confront the outward facing surfaces of the collars of the first shank. The holes of the collars can be aligned so as to allow the pin to pass through. The two shanks may be hinged together and act as a spring clasp.

PRIORITY STATEMENT

This application claims priority under 35 USC 119(a)-(d) to IN patentapplication No. 2755/MUM/2015, which was filed on Jul. 21, 2015, theentire content of which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention

This invention relates to the field of Jewellery manufacturing,particularly to a finger ring and more particularly to an adjustablefinger ring and the manufacturing of the same.

2. Description of Related Art

It is a common observation that due to change in blood pressure there isa tendency of fingers to swell and the ring requires adjustmentaccordingly to provide comfort.

A ring could not be presented to any one without knowing his/her exactsize. Accordingly exchanges or further modification is necessitated.

SUMMARY

Non-limiting embodiments of the invention may obviate the drawbacks inthe prior art. Such embodiments may provide one or more of the followingbenefits:

-   -   a) Ring automatically adjusts itself on different sizes of        finger.    -   b) Due to change in blood pressure there is a tendency of        fingers to swell, the ring adjusts accordingly to provide        comfort.    -   c) The ring could be presented to any one without modification        e.g. from grandmother to mother and granddaughter and so on.

According to a non-limiting embodiment, an adjustable finger ring mayinclude a ring head having through holes on the bottom, a first shankhaving shank collars as support at one end and a split portion at theother end, and a second shank having shank collars as support at one endand a split portion at the other end. The split portions may complementand overlap each other in an operative condition of the ring. A springmay be fitted inside the two supports, such that the coils of the springalign with the holes of the supports to allow a pin to pass through.Here, the inside surfaces of the collars of one shank may confront theoutside surfaces of the collars of the other shank, with the holes ofthe collars aligned so that the riveting pin can pass through, to makean assembly so that the two shanks are hinged together and act as aspring clasp.

According to a non-limiting embodiment, a method of making an adjustablefinger ring may involve inserting a coil spring between two firstcollars of a first shank, and aligning the coils of the coil spring withholes provided in the first collars. A second shank having two secondcollars may be positioned such that inward facing surfaces of the secondcollars confront outward facing surfaces of the first collars. Holesprovided in the second collars may be aligned with the holes in thefirst collars. A ring head with through holes may be positioned, suchthat the through holes are aligned with the holes in the second collars.A pin may be inserted through the through holes of the ring head, theholes in the second collars, the holes in the first collars, and thecoils of the coil spring. Both ends of the pin may be fixed to a bottomof the ring head.

DESCRIPTION OF NON-LIMITING EMBODIMENTS

With reference to FIGS. 1 and 2, an adjustable finger ring includes aring head (1) having through holes (20) on the bottom. The ring head (1)is supported by a first shank (2) and a second shank (5). Turning toFIG. 7, the first shank (2) has shank collars (6 a) as support at oneend and a split portion (6 b) at the other end. The second shank (5) hasshank collars (7 a) as support at one end and a split portion (7 b) atthe other end. As shown in FIGS. 5 and 6, the split portions (6 b) and(7 b) complement and overlap each other in an operative condition of thering.

A spring (4) is fitted between the collars of the shanks (2) and (5).The coils of the spring (4) are aligned with the holes of the collars (6a) and (7 a). And a riveting pin (3) extends through the pair of collars(6 a), the pair of collars (7 a), and the coils of the spring (4). Thecollars (7 a) of the second shank (5) are spaced apart farther than thecollars (6 a) of the first shank (2). Thus, the inward facing surfacesof the collars (7 a) confront the outward facing surfaces of the collars(6 a), and the inward facing surfaces of the collars (6 a) confront thespring (4). It will be appreciated that in the assembled condition, oneend of the spring (4) presses against the collared end of the shank (2),and the other end of the spring (4) presses against the collared end ofthe shank (5).

By virtue of the riveting pin (3), the two shanks (2) and (5) are hingedtogether and act as a spring clasp. The spring (4) influences the shanksto rotate about the pin (3) in a closing direction to the conditionshown in FIG. 2, in which the split portions (6 b) and (7 b) interact tolimit the movements of the shanks in the closing direction. If theshanks are rotated about the pin (3) in an opening direction and againstthe influence of the spring (4), then the overlapped split portions (6b) and (7 b) of the shanks will slide over each other and widen, whichresults in an increased size of the ring. If one reduces this pressure,then the spring (4) will influence the shanks to rotate about the pin(3) in a closing direction and regain the original position shown inFIG. 2.

By way of example only, the material chosen for the different parts maybe as given below:

Description Material Ring Head (1) Silver Shank (2) Silver Riveting Pin(3) Silver Coil spring (4) Hardened steel Shank (5) Silver

The method of making an adjustable finger ring may involve thefollowing. Insert the coil spring (4) between the two collars (6 a) ofthe first shank (2), and align the coils of the spring (4) with theholes of the collars (6 a).

Position the second shank (5), such that the inward facing surfaces ofthe collars (7 a) confront the outward facing surfaces of the collars (6a), and align the holes of the collars (7 a) with the holes of thecollars (6 a). This will complete stage two of the assembly.

Position the ring head (1) on the top of the assembly, as shown in FIG.4. And align the through holes 20 with the holes in the collars (7 a).This will complete stage 3 of the assembly.

Insert the pin (3) through the entire assembly and solder both ends ofthe pin on the through holes (20). In the assembled condition, both endsof the pin (3) are fixed at the bottom wall of the ring head (1).

The present invention is not limited to the above-described embodiments,and various alterations, modifications, and/or alternative applicationsof the invention may be possible, if desired, without departing from thescope and sprit of the invention, which can be read from the claims andthe entire specification. All of these possible alterations,modifications, and/or alternative applications of the invention are alsointended to be within the technical scope of the present invention.
